WOW that is cool.
Those guys look like they are returning home or perhaps out of range of enemy fighters and on the way to drop da bombs.
I know a lil about the B17s. The gunners are the real aces of WWII. They had more kills than any fighter ace. They flew the box formation to help reduce their losses. At the beginning of WWII the B17 was actaully faster than our fastest fighter at the time. Reminds me of Civil Air Patrol, I might have to go back to my roots.
